According to U.S. Geological Survey Earthquake Hazards Program, at 4:38am CDT, the epicenter of the quake was felt from St Louis, Missouri to Detroit Michigan.

A 5.4 earthquake that appeared to rival the strongest recorded in the region rocked people awake up to 350 miles away early Friday, surprising residents unaccustomed to such a powerful Midwest temblor.

The quake just before 4:37 a.m. was centered 6 miles from West Salem, Ill., and 66 miles from Evansville, Ind. It was felt in such distant cities as Chicago, Cincinnati and Milwaukee, 350 miles north of the epicenter, but there were no early reports of injuries or significant damage.

"It shook our house where it woke me up," said David Behm of Philo, 10 miles south of Champaign. "Windows were rattling, and you could hear it. The house was shaking inches. For people in central Illinois, this is a big deal. It's not like California."

The quake shook skyscrapers in Chicago's Loop, 240 miles north of the epicenter, and in downtown Indianapolis, about 160 miles northeast of it. Residents of Cincinnati and St. Louis also reported feeling the earth shake.
